The large stroke shaft jacking device acts on the connecting pin shaft by utilizing a hydraulic principle, the equipment damage problem caused by the fact that a worker uses a sledge hammer to detach the pin shaft so that an equipment connecting piece is subjected to strong impact or vibration is solved, the safety performance is high, the operation is simple and convenient, and the working efficiency is improved.
Description
Technical field
The utility model belongs to main equipment maintenance technique field, relates generally to a kind of large stroke jacking shaft device.
Background technology
The main equipment that surface mine uses is more, and equipment very easy wearing and tearing of bearing pin that on equipment, connecting portion plays connection function in long-term use procedure needs on-call maintenance to change.But in plant maintenance process: connect bearing pin while changing connecting axle and be difficult to take out, the method adopting in maintenance sites is at present manually to use sledgehammer that bearing pin is got, while beating bearing pin, strong impact or vibration force can cause damage to equipment both sides connector, shortened the service life of connector.
Utility model content
In view of existing problem in prior art, the utility model proposes a kind of large stroke jacking shaft device, can steadily take out and can not cause any impact or vibration to attaching parts connecting bearing pin, alleviate operating personnel's labour intensity, improve operating efficiency.In order to realize foregoing invention object, technical solution adopted in the utility model is: a kind of large stroke jacking shaft device is mainly hydraulic part, bracing frame, hook formation; Wherein hydraulic part is made up of fuel reserve tank, cylinder body, piston rod, relief valve, inlet valve, depression bar frame, depression bar, and inlet valve is equipped with in position in fuel reserve tank bottom centre, and relief valve is equipped with on the oil storage casing left side; Depression bar by depression bar frame be arranged on fuel reserve tank above, the cylinder body that outer surface is Design of Screw Thread is arranged on below fuel reserve tank, and piston rod is housed in cylinder body; Three bracing frames that arm lengths is identical, angle is equal are connected with hydraulic part by cylinder body external screw thread, can up-down adjustment; On bracing frame, be designed with lateral adjustments hole, three hooks are separately fixed on three arms of bracing frame with connection bearing pin, are designed with vertical adjustment hole on hook; The large stroke jacking shaft device of described one, wherein the adjustment stroke in lateral adjustments hole is 1000mm to 2000mm; The large stroke jacking shaft device of described one, wherein the adjustment stroke in vertical adjustment hole is 1500mm; The large stroke jacking shaft device of described one, wherein the top power of piston rod is 10T.
The large stroke jacking shaft device of one described in the utility model, utilizing hydraulic principle to act on the maximum top power connecting on bearing pin is 10T, the connection bearing pin on extraction device easily.Laterally for the adjustment stroke of 1000mm to 2000mm be vertically that the adjustment stroke of 1500mm can be used in and anyly has on the equipment and parts that bearing pin is connected, and can regulate hook position according to the thickness of parts and equipment, there is applied range, security performance feature high, easy and simple to handle, reduce labour intensity, improved operating efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of the utility model bracing frame.
In figure: 1, fuel reserve tank; 2, cylinder body; 3, piston rod; 4, relief valve; 5, inlet valve; 6, depression bar frame; 7, depression bar; 8, bracing frame; 9, connect bearing pin; 10, lateral adjustments hole; 11, hook; 12, vertical adjustment hole.
The specific embodiment
Provide the specific embodiment of the present utility model below in conjunction with accompanying drawing as follows:
As shown in Figure 1 and Figure 2, the large stroke jacking shaft device of one described in the utility model, is to be mainly made up of hydraulic part, bracing frame 8, hook 11; Wherein hydraulic part is made up of fuel reserve tank 1, cylinder body 2, piston rod 3, relief valve 4, inlet valve 5, depression bar frame 6, depression bar 7, inlet valve 5 is equipped with at fuel reserve tank 1 bottom centre position, relief valve 4 is equipped with on the fuel reserve tank 1 casing left side, depression bar 7 by depression bar frame 6 be arranged on fuel reserve tank 1 above, outer surface is that the cylinder body 2 of Design of Screw Thread is arranged on below fuel reserve tank 1, and piston rod 3 is housed in cylinder body 2; Three bracing frames that arm lengths is identical, angle is equal 8 are connected with hydraulic part by the external screw thread of cylinder body 2, can up-down adjustment, on bracing frame 8, be designed with lateral adjustments hole 10, and the adjustment stroke in lateral adjustments hole 10 is
1000mm to 2000mm; Three hook 11 use connect bearing pin 9 and are separately fixed on three arms of bracing frame 8, on hook 11, be designed with vertical adjustment hole 12, the adjustment stroke in vertical adjustment hole 12 is 1500mm, bracing frame 8 and hook 11 can pass through lateral adjustments hole 10, vertical adjustment hole 12 adjustment stroke, and the top power of piston rod 3 is 10T.The course of work of described a kind of large stroke jacking shaft device is: first relief valve 4 rotational lock in the direction of the clock, then by vertical adjustment hole 12 on hook 11, hook 11 is carried out to large-scale distance adjustment, hook 11 is adjusted to bearing pin connecting portion, do not reach adjusting requirement if regulated, can carry out up and down the Anhui musical styly by cylinder body 2 external screw threads, make hook accurately adjust to operating position.By the lateral adjustments hole 10 on bracing frame 8, piston rod 3 is adjusted on the position that withstands on bearing pin, swung up and down depression bar 7 cylinder body 2 oilings to fuel reserve tank 1 bottom, piston rod 3 steadily advances under the effect of oil pressure, being ejected by ejector pin axle.While regaining piston rod 3, only need be by counterclockwise unclamping relief valve 4, piston rod 3 can bounce back gradually under hydraulic action.If the connector of bearing pin is thinner, for avoiding damaging connector, can adds in hook 11 bottoms and regulate with liner.
